Udemy, you will find, provides a number of different online courses, both free and paid. Some of the paid courses will be a little more in-depth, but for those who are here for free courses (I know I am), then they have more than enough for you, too. They offer free courses in Google AdWords, Zero Cost Marketing Strategies, Content Marketing, and Social Media Marketing, and even provide a course on SEO, or Search Engine Optimization, so you can learn how to utilize keywords in your marketing and reach a wider audience.
If you have a spare bedroom, you can find a roommate or list the space on AirBnB for travelers. Having a roommate is the more passive of the two, as being an Airbnb host will require more work in the form of turning over the room between stays. This is a super painless way to earn $500 to $1,000 a month without much effort – you may even be able to cover your mortgage payment with this extra income!
If you create a website and have the top navigation bar be all the different types of lenses (wildlife lenses, sports lenses, portrait photography lenses, etc) and then make drop down menus for the different brands of cameras, you could create a site where people come, choose what brand of camera they have and what they want their lens to do and viola! You have a page on your site that shows them the good, better, and best lens options at different price points. This kind of site could be really popular and insanely useful. That’s a recipe for success.
